WRENCH FOR VEHICLE-NUTS.

Specification of Letters Patent.

Patented Aug. 20, 1907.

Application filed April 23,1907. Serial No. 369,732.

To all whom it may concern:

Be it known that I, FEDELE T. MUsso, a citizen of the United States, residing at Bowman, in the county of Placer and State of California, have invented certain new and useful Improvements in Wrenches for Vehicle-Nuts; and I do declare the following to be a full,

- clear, and exact description of the same, such as will .will retain the nut and wrench in the hub of the wheel when unscrewed, thus preventing the same from falling in the dirt or soiling or dirtying the owners hands or clothes.

These main objects and many minor ones I accomplish by means of a wrench having a pliable band disposed around it, which band bears against the inner periphery of the hub band, thus holding the wrench and incidentally the nut bound in said hub; also by such other and further construction as will appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indi cate corresponding parts in the several Views.

Figure l is a sectional view of a fragmentary portion of a vehicle hub showing my improved device inserted therein. Fig. 2 is a rear elevation of my improved device. Fig. 3 is a side elevation of the same. Fig. 4

is a front elevation of the device. Fig. 5 is a View similar to Fig. 2 with certain parts removed.

Referring more particularly to the reference numerals on the drawings 1 designates the spindle of a vehicle, there being a wheel hub 2 mounted thereon, the said spindle carrying the usual nut 3.

4 designates the jaw of the wrench which has a circular periphery 5 provided with a circumferential groove 6 in which is cemented, or otherwise secured, an elastic member consisting of a rubber band or tire 7. Held outward from the portion 4 by arms 8 is a cross member 8 forming a slot 9 therebetween. Mounted in the cross member 8 is a set screw 10 for the purpose hereinafter set forth.

In practice when it is desired to remove the wheel for oiling the spindle, the jaw 4 is inserted over the nut 3, the band 7 gripping snugly against the inner periphery of the hub band. Any suitable bar, for instance a Wrench 11, which is the mostconvenient, would then be inserted into the slot 9, and secured by set screw 10,

and is brought to bear on the arms 8, which loosens the said nut. The whole wheel is then rotated rapidly. This op eration unscrews the nut from the spindle, since the band 7 holds the wrench stationary in the hub, thus causing the nut to be rotated with the wheel.- When the nut is completely unscrewed and the wheel removed, the nut and wrench is retained in the hub by means of the said band 7. When the vehicle is lubricated the nut is started on the spindle and then the wheel is rotated rapidly, thus screwing the nut up into place. When said nut is screwed up into position and stops, the elasticity and pliability of the band 7, permits the wheel to continue its rotation independent of said wrench, thus preventing any sudden jolt on the parts, which, of course, would be more or less injurious. In practice the wrench 11 might be formed as a component part of the wrench 4, thus forming a wrench which might be used for many purposes in addition to the main one just described. Also instead of a continuous band 7. the same may be formed of a plurality of separate bearing points.

Thus it will be seen that I have produced a device that substantially fulfils all the objects of the invention as set forth herein.

While in this specification I have set forth in detail the present and preferred construction of my device, still in practice many small deviations from such detail may be resorted to as will not amount to a departure from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent 1s:

1. In a device of the character described a wrench, the I jaw thereof having an outer circular periphery, a groove following the outer face of the periphery, and means secured in said groove for retaining said wrench in a hub of a vehicle as set forth.

2. A wrench comprising a circular perforated jaw having a circumferential groove, an elastic member secured in and projecting from said groove adapted to engage the in ner face of the hub band of a vehicle wheel.

3. A wrench comprising a nut engaging jaw having an outer curved surface provided with an annular groove, an elastic member secured in said groove and contacting the inner surface of the hub band of avehicle wheel, a cross member mounted upon parallel arms carried by said jaw and suitably spaced from the latter forming a slot therebetween, a lever disposed in said slot and a set screw arranged in said cross member.

In testimony whereof I afiix my signature in presence of two witnesses.
